Reliability by Source

Each independent organization measures reliability differently. TÜV reports inspection defect rates by age band. ADAC reports pan-European breakdowns per 1,000 vehicles. NHTSA aggregates US consumer complaints. DVSA MOT data is the UK fleet's annual safety inspection — every car 3+ years old. Lower variance across sources = higher confidence in the composite.

Known Issues

Specific failure modes documented across European workshops, owner forums, and TSBs. Costs in EUR (and USD reference) reflect typical retail European labor + parts ranges — specialist shops at the low end, dealer pricing at the high end.

Tailgate rust on Estate (W211/W212)
Typical at 80,000–200,000 km
W211 (and to lesser extent W212) Estate tailgates rust around the number-plate light cluster and lower edge; cosmetic at first, structural eventually.
€400–€1,500medium
Air suspension (AIRMATIC) leak / strut failure
Typical at 100,000–200,000 km
W212/W213 AIRMATIC equipped models — air strut perish + valve block leaks; whole-corner replacement is the right repair.
